Particularly in such. systems as gasify the fuel before burning h isthere tinues. These are recognized causes of danger and: are to be avoided,

In accordance with my invention I provide a system in which there is a cut oil op erable by any initial overflow of liquid fuel due to extinguishment or otherwise. For the purposes of illustration I have selected a simple form of system and cut off which I have found well adapted topractical use and I will discuss my invention with reference to such a system as both illustrative of the principles involved and as showing convenient and practical apparatus well adapted to use. Throughout the specification and drawings like reference characters are employed to indicate corresponding parts and in the drawings:

Fig. 1 is a general view of such a system.

Fig. 2 a view of the cut ofl' apparatus, and

Fig. 3 a detail section of the cut off valve for the same.

- In the system shown I have indicated at 1 a tank as a source of supply for a gravity feed line 2 leading to a gasifying chamber 3 which feeds a burner 4. These I have shown as located in the fire box of a, range although it will be understood that the burner may be of any type and used with any kind of a range, heateror even fireplace.

Cut in on the feed line 2 is a cut off consisting of a small chamber 5 into the bottom of which the feed line 2 enters through a valve seat fitting 6 raised slightly above the bottom level. I Guided in the top of the chamber 5 is a valve stem 7 having a ground.

valve end/7 which cooperates with the valve.

Theor m t fedp pe 2' is? b efh th which the chamber can be drained.

Pivotedto 11 one'side thechamber 1S1}. lever 11 weighted. as atfW at its/long provided to, make adjustment so that when the lever .11, "is raised/its weight W will stand just back oi thevertical' of itspoint of Pivot a e thu mainta in ais d P sition; In other words. the 'lever11-vvhen raisedto full positionshown inFig. 2 isjj ust eneugh 0E center n. i s piv v so; a t be mainta ne s re i i i by: grav ty and anrlhaving its short end providedwith v ndfb arine en the nees e i at the Trbdi The chamber 5 issupported' on a low' stand 12 so that it can be conveniently located with respect to the burner. From the pan P of the burner a drain pipe 16 leads adjacent the cut off where it terminates over the removable cup 13 which fits in a holder 13 on a lever 14 fulcrumed at 14. to the stand 12.

From the opposite end of the lever 14:

rises a release rod 15 the upper end 15 of which can be positioned in the notch 11 of the lever 11. i

IVhen now the burner is lighted and the system is in proper operationwith the burner lighted, the liquid fuel flowing to the vaporizing chamber 3 is converted to gas and burned at the nozzle 1. If the flame be extinguished and be not immediately relighted the chamber 3 cools and the fuel flows through the nozzle 4: and floods g I the pan P. I i

The overflow passing through the pipe 16 begins to fill the cup 13 I usually provide the balance and leverage so that 2' or 3 oimces of oil will be sufficient to counterbalance the weight W of the lever '11 so that it will be tipped forward and fall on I 0f the burner I provide at the top of-the chamber 5 suitably insulated binding posts 17 having bent spring contacts 17 The lever 11 is provided with a cross pin' 18 which acts as a circuit closer for any suitable circuit as C. This may conveniently be cut in on the circuit of a door or service bellrB which will continue to ring as long as the burner remains accidentally extin guished. Such a cut oif is simple andinexpensive and affords an important factor of safety in such systems.

Various modifications in the form and arrangement of cut'oii' and its position may be made; It may also be combined in various systems and all without departing from: the spirit of my invention if within the limits defined in the claims.

What I therefore claim'and desire 'to secure by Letters Patent is r 1. A gravity actuated out off for a supply system, comprising a valve, resilient means for holdingsaid valve'open, a weighted arm pivoted adjacent thereto and disposed to contact the valve stem in its'fall, said arm having a stop for positioning it in raised "position just back of its center of gravity,

a pivoted lever, a drip pan on one end of said lever, and a push rod connected to the other end of said lever, and having one end engaging said arm to the rear of its center of gravity whereby it may be tipped beyond said center upon the loading of the pan.

2. A gravity actuated cut off for a supply the loading of the pan.

system, comprising a reciprocating valve,

pan on one end of said lever, and a push rod adj ustably connected to the other end of said lever, and having one end engaging saidarm to the rear oiits center of gravity whereby it may be tipped beyond said center upon 1 3. A gravity actuated'cut off for a pressure supply system, comprising a reciproeating-valve, a pro ecting stem on'the valve,

resilient means for holding the stem in projected position, a weighted armpivoted adjacent thereto and disposed to contactthe valve stemin its fall, said arm having a stop for positioning it in raised position just back of the center of gravity, a pivoted lever, a drip pan on one end of said lever, and a contact between said lever and said arm having one end engaging said arm slightly to the rear of its center of gravity, whereby it may be tipped beyond .said center upon a slight loading of the pan.

In testimony whereofI aflix my signature.
